Application and users

The Pomona 2249-C-12 is a 12 in BNC coaxial cable built for test, measurement and RF signal paths. It suits technicians and engineers who need a short, shielded run between instruments, panels or modules.

Interface limits

The cable carries signals from DC to 4 GHz with a 50 Ohm impedance and is rated to 500 Vrms. Its 20 AWG centre conductor and PE insulation set the practical ceiling for frequency response and voltage handling.

Build and daily use

Nickel-plated brass connectors and a black jacket withstand a temperature range of -104 to 185 degrees Fahrenheit. The male-to-male BNC ends lock securely, so the link stays firm during bench work or rack installation.

Questions about this item

Should I choose the 12-inch length or a longer BNC cable?

The 12-inch length suits tight bench setups or short rack runs; choose a longer cable only if the devices sit farther apart.

What does the 4 GHz frequency range mean when I connect this cable?

It carries signals cleanly from DC up to 4 GHz, so it handles typical RF, video and test equipment bands without significant loss.

The cable uses BNC connectors — what does the 50-ohm impedance cap in practice?

The 50-ohm impedance matches standard RF gear, preventing reflections up to the rated 4 GHz when both ends are terminated in 50 ohms.
